First, tort reform. Cost to the taxpayers - exactly zero. Benefit to the taxpayers, about 25 cents reduction per dollar of health care.
Next, insurance competition. Pass a law to enable people to buy insurance across state lines. Cost to the taxpayer - exactly zero. Benefit to the taxpayer, insurance companies are no longer state-supported monopolies; competition brings down rates.
The buying insurance across state lines. I forgot about that one. Excellent idea.
